My version of CInema 4D began crashing after I did graphic driver updates. It crashes on any type of renderer I have tried to use and not even rolling back the gpu drivers fixed the issue. At first it started off with black screen instead of the viewport and had to disable OpenGL in settings to get the viewport back.
Running i7 5930K (Not overclocked) and GTX 1080. No 3rd party plugins and the install of C4D is only a few months old because did total computer reinstall.
